"So, can you tell us more about what you've eaten in the past two years?"
The doctor's words were calm and detailed, and he seemed very professional, and he was sitting in front of the computer, ready to record the patient's eating habits. Mr. Zhang and Ms. Li sat opposite each other, their faces solemn. They had just been told the same heavy news from the same hospital one after another: cancer.
There is nothing special about this ordinary middle-aged couple, Mr. Zhang is an elevator maintenance worker, and Ms. Li is a secondary school teacher. Such a profession makes their lives regular and ordinary, and the only difference may be their eating habits in the past two years.
"We don't really have anything special, we just love to eat barbecue and pickled food. Mr. Zhang said helplessly, while Ms. Li nodded in agreement. The aroma of barbecue and the convenience of pickled food have always been a blessing in their busy lives.
After hearing this, the doctor's face became a little solemn and began to explain in detail why these two foods would affect their health.
"Barbecued and pickled foods contain high amounts of polycyclic aromatic hydrocarbons and nitrites, chemicals that can form strong carcinogens in the human body. ”
When the doctor said this, his eyes did not take his eyes off the faces of Mr. Zhang and Ms. Li, as if to see if they could understand the seriousness of the situation. He continued, "Polycyclic aromatic hydrocarbons (PAHs) are mainly derived from the deposition of food in smoke during high-temperature grilling, while nitrite is a chemical additive widely used in preserved foods. ”
Mr. Zhang and Ms. Li listened attentively, and this was the first time they had learned about the potential harm of these everyday foods from a scientific perspective. "Long-term consumption of excessive amounts of these foods is associated with a significantly higher incidence of cancer than the general population. ”
The doctor pulled up a set of data from a computer that showed statistical evidence of a link between ingestion of these substances and cancer. "How can we change our eating habits?"
The doctor smiled and began to detail the recommendations for a healthy diet. "First of all, try to avoid the intake of high-temperature barbecues and long-marinated foods,
Second, increase the proportion of fresh vegetables and fruits, which are rich in fiber and vitamins that can help lower carcinogens in the body. ”
He also pointed out that drinking as much water as possible can boost metabolism and speed up the elimination of harmful substances from the body.
In addition, the doctor specifically mentioned a little-known but extremely valuable opinion: "In fact, ordinary black tea contains a special antioxidant compound that can effectively neutralize some carcinogens. ”
This is something that few people are able to gain from regular health knowledge. After hearing this, Mr. Zhang and Ms. Li became interested in black tea.
Throughout the consultation, the doctor used his colloquial and vivid expression to make the complex medical knowledge easy to understand. Mr. Zhang couldn't help but ask a question: "So, can drinking black tea for a long time really prevent cancer?"
The doctor replied seriously: "It is true that the antioxidants in black tea can reduce the harm of some carcinogens, but cancer prevention also requires comprehensive lifestyle adjustments. Drinking tea alone is not enough. He further explained the mechanism of action of antioxidants.
